How to adjust a Pozis refrigerator: step-by-step instructions with photos and expert advice

Refrigerators Pozis have long proven themselves to be reliable and functional devices, but even the most advanced equipment requires proper adjustment. Incorrectly set temperature leads to overfreezing of food, ice formation on the walls or, conversely, insufficient cooling. In this article, we will look at how to adjust a refrigerator Pozis of different series - from mechanical models with rotary knobs to modern devices with electronic controls and a display.

You will learn what parameters are considered optimal for the refrigerator and freezer compartments, how to avoid typical mistakes when setting up, and what to do if, after changing modes, the equipment is unstable. We will pay special attention to the nuances for popular lines Pozis RK, Pozis FK and Pozis Frost Free, and we will also look at how the system No Frost and function Super Freeze.

Important: if your refrigerator Pozis was produced before 2010, some recommendations may not be suitable - older models used different principles of thermoregulation. For precise settings, check the instructions for the specific modification.

1. Optimal temperature conditions for the Pozis refrigerator

Before turning the controls, decide what temperature you need. The manufacturer Pozis recommends the following ranges:

• 🥦 Refrigerator compartment: from +2°C to +5°C. Optimal - +4°C for most products.
• ❄️ Freezer: from -18°C to -24°C. For long-term storage (meat, fish), choose -20°C.
• ⚠️ Zone freshness (if available): usually 0°C to +1°C - for greens, cheeses, sausages.

Why exactly these values? At +2°C the products freeze slightly, losing their taste, and above +5°C the active proliferation of bacteria begins. In the freezer, the temperature lower -24°C leads to excessive load on the compressor and increased energy consumption.

In Pozis models with the No Frost system, the temperature difference between the shelves can reach 2-3°C - this is normal. To compensate for this, place perishable products (dairy, meat) on the middle shelves, where the cold is distributed more evenly.

If your model Pozis has a function "Vacation" (for example, in the series FK-101), when activated, the temperature in the refrigerator compartment rises to +12°C - this saves energy, but is only suitable for short-term downtime (up to 2 weeks).

2. Mechanical adjustment: Pozis models with rotary knobs

Most budget refrigerators Pozis (for example, RK-102, FK-140) are equipped with a mechanical thermostat - a plastic or metal knob with a digital scale from 1 to 7 (less often up to 9). The higher the number, the colder it is in the chamber.

How to set:

1. Find the regulator - usually it is located inside the refrigerator on the right wall or on the top panel (in models with a freezer at the bottom).
2. Turn the knob clockwise to decrease the temperature, against - to increase.
3. Wait 6-8 hours until the temperature stabilizes (the compressor should turn off).
4. Check the result with a thermometer (put it in a glass of water on the middle shelf).

Typical mistakes:

• ❌ Setting to maximum (7) in the summer “just in case” - this leads to icing of the evaporator and increased wear on the compressor.
• ❌ Adjustment immediately after defrosting - wait until the equipment reaches operating mode (minimum 2 hours).
• ❌ Ignoring external factors: if the refrigerator is standing next to the stove or window, even 3–4 it can freeze.

Advice for models with one regulator for both chambers (for example, Pozis RK-139): if the freezer is working normally, and in the refrigerator compartment too cold, check the door seal - perhaps it lets warm air in and the thermostat works more often.

Make sure the door closes tightly (check with a sheet paper)|

Disable the "Super Freeze" function (if available)|

3. Electronic control: setting via display

In refrigerators Pozis premium series (Frost Free, Inverter) an electronic control unit with touch buttons or a display is used. For example, in the model Pozis RK-167 NF the temperature is adjusted separately for each chamber in steps of 1°C.

Step-by-step instructions:

1. Press the button Temp (or Fridge for the refrigeration camera Freezer for the freezer).
2. Use the buttons +/– or touch arrows to set the desired value.
3. Confirm the selection (in some models the setting is saved automatically after 5 seconds).
4. On The display will show the current temperature - after 1-2 hours, check it again.

Features of electronic models:

• 🔄 Function "Auto-defrost" can temporarily increase the temperature in the freezer to -12°C —this is normal.
• ⚡ In inverter refrigerators (for example, Pozis Inverter FK-200) the compressor works continuously, but with different powers - do not be alarmed by the quiet hum.
• 📊 Some models save a history of temperatures - this helps to track when they started failures.

If after setting the indicator blinks on the display Alarm or Hi/Lo, this is a signal of a malfunction. First of all, check:

• The tightness of the door closure (perhaps the seal or dishes are in the way).
• Is the freezer overloaded (air circulation in No Frost is disrupted if food blocks the ventilation holes).
• Is it worth it? the refrigerator is close to the wall (a gap of at least 5 cm is needed).

What to do if the display shows the wrong temperature?

If the actual temperature (measured by a thermometer) differs from the display readings by more than 3°C, sensor calibration is required. In Pozis models with electronic control, this is done through the service menu:

1. Unplug the refrigerator for 1 minute.
2. Hold the Temp and Super Cool buttons simultaneously for 10 seconds.
3. B in the service menu, select the item Calibration (use the buttons +/– to navigate).
4. Reset the sensor settings to factory settings (Reset).

After calibration, wait for the compressor to complete the operating cycle (4-6 hours).

4. Adjustment in Pozis refrigerators with the No Frost system

Models with No Frost (for example, Pozis RK-185 NF, FK-220 NF) do not require defrosting, but the temperature setting in them has nuances. The main difference is forced air circulation, which is why the cold is distributed more unevenly than in drip refrigerators.

Recommendations for No Frost:

• 🌬️ Do not place food close to the back wall - this will block the air flow.
• 🥶 Set the temperature 1–2°C lower than in drip models (for example, +3°C instead +4°C).
• ❄️ Turn on the function "Super Freeze" 6-12 hours before loading a large volume of products, and then turn it off.

B refrigerators Pozis with No Frost the problem of a “warm” top shelf is often encountered. This happens due to:

• An air duct clogged with dust (needs cleaning).
• A faulty fan (listen - it should hum quietly when operating). compressor).
• Incorrect operation of the damper between the chambers (in models with one compressor).

How to check the damper:

1. Turn off the refrigerator.
2. Remove the back panel in the refrigerator compartment (usually it is attached to latches).
3. Find the plastic damper - it should open and close freely. If it is jammed, clear the mechanism of ice or replace the spring.

5. Seasonal adjustment: summer and winter

The room temperature directly affects the operation of the refrigerator. Pozis recommends adjusting the settings depending on the season:

⚠️ Attention: if the refrigerator Pozis is in an unheated room (for example, in a country house in winter), at a temperature below +10°C the oil in the compressor thickens, and the equipment may not turn on. In this case:

• Use a heater to maintain +15°C around the refrigerator.
• Disable the function No Frost (if equipped) - at low temperatures it does not work correctly.
• Do not store food in the freezer for more than 1 month - due to unstable temperatures, they may spoil.

On hot days (above +30°C), the refrigerator Pozis can work without stopping. This is normal, but to reduce the load:

• 🔌 Disable "Super Freeze".
• 🚪 Minimize door opening.
• 💡 Replace the incandescent lamp with LED (if any) - it heats up less.

6. Typical problems after adjustment and their solution

If after changing the settings the refrigerator Pozis is unstable, use this table for diagnostics:

⚠️ Attention: if, after adjustment, the refrigerator Pozis makes clicks or crackling, this may be normal - this is how the compressor relay operates. But if the sounds are repeated more than once every 5 minutes, check:

• Network voltage (should be 220V ±10%).
• The state of the starting relay (when overheated, it clicks more often).
• Oil level in the compressor (if there is a leak, a metallic knock is heard).

What to do if the refrigerator does not respond to adjustment?

1. Disconnect it from the network for 10 minutes - this will reset the electronic unit.
2. Check whether the power indicator is on (if no - the problem is in the power filter).
3. In mechanical models, try to slightly move the thermostat knob - sometimes the contacts oxidize.

7. Adjustment in two-chamber Pozis refrigerators

Two-chamber models (Pozis RK-143, FK-170) can have both one compressor for both chambers and two separatethe adjustment process depends on this: data-i="271">one compressor

One compressor (for example, Pozis RK-130):

• The temperature is regulated one thermostat, but the cold is distributed through the damper.
• If it is too cold in the freezer and warm in the refrigerator compartment, check the damper (see section 4).
• Optimal mode: regulator on 3, freezer on -18°C.

Two compressors (for example, Pozis FK-201):

• Each chamber is configured independently.
• In the freezer you can install -24°C for long-term storage, and leave it in the refrigerator compartment +4°C.
• Energy consumption is higher, but the accuracy of maintaining the temperature is better.

⚠️ Attention: in two-compressor models Pozis when one chamber is turned off (for example, a freezer for the summer) you cannot:

• Leave the door open - this will lead to condensation and rust.
• Store food in a disconnected chamber - the temperature inside will rise to room temperature.
• Use the chamber for drying clothes or heating - this disrupts the microclimate.

If your model has a function "Cool Select Zone" (for example, in Pozis RK-190), it can be controlled separately:

• 🥩 Meat mode: 0°C — for short-term storage of raw meat.
• 🧀 Cheese mode: +2°C — for hard cheeses and sausages.
• 🍷 Wine mode: +10°C —for bottles (only in some models).

8. When adjustment does not help: signs of malfunctions

If you have configured the refrigerator correctly Pozis, but the problem remains, repair may be required. Pay attention to these symptoms:

• 🔴 The compressor is running more than 20 minutes without stopping —the thermostat is faulty or there is a freon leak.
• ❄️ On the back wall, a "fur coat" thicker than 5 mm is formed - the capillary pipeline is clogged.
• 💨 The fan in No Frost does not turn on - check its power supply (there should be 12V).
• 🌡️ The temperature in the chambers differs from the set one by more than 5°C —the sensor is faulty.

Self-diagnosis:

1. Ring the thermostat with a multimeter:

   Set the resistance test mode (200 Ohms).
   At room temperature there should be 0 Ohms between pins 3 and 4.
   If the resistance does not change during cooling, the thermostat is faulty.

2. Check the voltage on the compressor:

   There should be 220V at the terminals when the relay is on.
   If there is voltage, but the compressor does not start, it has burned out winding.

⚠️ Attention: in refrigerators Pozis with electronic control not allowed replace sensors or control boards without special equipment. Incorrect soldering or connection will lead to firmware failure.

If you are not confident in your abilities, contact the service center. Average repair cost:

• Replacement of the thermostat: 1,500–2,500 ₽.
• Refilling with freon: 3,000–5,000 ₽.
• Repair of electronic unit: 2,000–4,000 ₽.

FAQ: Frequently asked questions about adjusting Pozis refrigerators

Is it possible to set different temperatures on the shelves in the refrigerator camera?

In most models Pozis this is not possible - the temperature is controlled centrally. However, in refrigerators with multi-flow system (for example, Pozis RK-200 MF) the cold is distributed more evenly, and the difference between the shelves is minimal (1–2°C). To compensate for this, place products according to the table in section 1.

Why did ice appear in the freezer after adjustment, and did it become warmer in the refrigerator?

This is a typical problem for single-compressor models Pozis with the system No Frost. The reason is a faulty shutter between the chambers. Cold air does not enter the refrigerator compartment, and the compressor runs idle, freezing the freezer. Solution: Defrost the refrigerator for 12 hours, then check the damper movement (see section 4). If the problem persists, you need to replace the damper or its drive.

How to reset the settings to factory settings in electronic models?

In refrigerators Pozis with a display, the reset is performed as follows:

1. Unplug the refrigerator for 1 minute.
2. Hold the Freezer and Fridge buttons simultaneously for 10 seconds.
3. The display will show rSt - confirm the reset with the button OK.

In mechanical models, factory settings are reset automatically when the power is turned off for 5+ minutes.

Do I need to adjust the temperature in the Pozis refrigerator after moving?

Yes, definitely! During transportation, the following could occur:

• Displacement of the compressor (leads to vibration and noise).
• Damage to the door seal (breaks the tightness).
• Failure of the electronic unit (in models with a display).

After installing the refrigerator on new place:

1. Wait 4-6 hours before turning on (to stabilize the oil in the compressor).
2. Check the level (should be level, without distortions).
3. Adjust the temperature again, starting with average values (3 or +4°C).

Is it possible to turn off the freezer in a Pozis refrigerator for the summer?

In two-compressor models - yes. To do this:

1. Press the button Freezer Off (or install temperature 0°C).
2. Defrost the chamber and wipe dry.
3. Leave the door ajar (for example, place a plug) to avoid mold.

In single-compressor refrigerators, you cannot completely turn off the freezer, but you can minimize its operation:

• Set the regulator to 1.
• Do not load food.
• Defrost periodically (once every 1-2 months).
